My invention relates to hair driers, such as are in use in beautyparlors, and conslsts in novel housing, operating structure and switcharrangement.

One of the objects of 1n y invention is to p rovide a housing or casingfor the operatlng parts which will be simple and of neat appear-ance,strong and easily cleaned.

Another object of my invention 1s to arrange a motor, a fan, heatingelements and a therapeutic lamp in such relation that the air currentscreated by the fan will pass over the motor, tending to cool the same,will receive the maximum amount of heat from the heating element andfrom the lamp, and will be directed from the drier with a minimum amountof interference in their passage therethrough.

Another object of my invention 1s to arrange the circuits and controlswitches therefor so that the device may be most easily and effectivelyoperated.

In the accompanying drawings which illustrate a selected embodiment ofmy invention- Figure 1 is a longitudinal vertical section through mydevice.

Figure 2 is an elevation of the left hand end of the device asillustrated inr Figure l. Figures 3 and 4 are vertical sections taken onthe lines 3 3 and 4 4 of Figure 1.

Figure 5 is a wiring and switch diagram.-

The housing or casing 1 is of cylindrical cross section and 'cncloses aring-like frame 2 having a plurality of spokes 3 extending inwardly fromits perimeter and mounting the motor frame 4 at their inner ends. Theleft hand endlof the motor shaft 5 mounts the fan 6 and the right handend of the motor 10 frame mounts a pair of perforated plates 7 whichgrip the inner portion of an insulator member 8 which carries theheating elements 9 and 10 on a series of radial arms 81.

A perforated reflector 1l is also attached to the motor frame, thisplate and plates 7 and 8 being secured to the frame by a screw 12.Atherapeutic lamp 13 is mounted on a socket 14 attached to the casing 1to the right of insulator 8. Y

The left hand end of the casing, although y which tends to reduced indiameter, is provided with a substantial opening which may be closed bya suitable plate 15. This plate mounts the switches 15, 16, 17 and 1,8and the rheostat 19. The switch and the rheostat knob project throughplate 15, as best shown in Figure l. The wiring of the device is allcontained Within the casing 1, except the leadf'in cable 20 and thecable' 2l leading from the front of the device to the lamp socket 14.

The device, as a whole, is preferably mounted upon a yoke 22 by means ofscrews 23 extending through the ends of the yoke arms and the casinginto frame 2.

By reference to the wiring diagram shown in Figure 5, it will be seenthat the switch 18 for the motor must be closed before either of theheating elements can function as the heating elements each have oneyterminal connected to the wire on the inner side of switch 18. Thisinsures the operation of the fan whenever one of the heating elements isturned on and avoids undesirable heating of the device, due to carelessinattention to the heat switches 15 and 16. 75

It is obvious, however, that` the motor may be turned on without any ofthe heating elements being turned on. The same is true of the lamp 13 asits switch 17 is independent of the motor circuit.

The casing 1 is freely perforated at its left hand portion, as indicatedat 24, and these perforations, together with the open construction ofthe motor supporting elements and the supports for theheating-elements'and the reflector for the lamp 13, make for freepassage of the air through the device coolthe rheostat, cool the motor,and heat the air to the maximum degree for a given amount of current.

The mounting of the switches and rheo`V stat on the removable plate atthe left hand" end of the casing enables the casing to be producedwithout any unsightly crevices and fastening devices or additional boxesfor 95 housing the elements for controlling the electrical apparatus andalso provides for ready access to the switches and wiring in case the .fsame need attention.

Obviously in a device of this kind, many ments in the of the details maybe varied without departing from the spirit of the invention and Icontemplate such modifications in the structure as come within the scopeof my claims.

I claim:

1. In a device of the class described, a frame member, a motor mountedon said member, a fan on one side of said frame and driven by saidmotor, a pair of clamping elements secured to said motor on the otherside of said frame, an insulator gripped between said elements, areflector in front of said elements, and a rlamp in front of saidreflector, said frame, elements, insulator and reflector beingconstructed to allow an air stream to pass through the same and ast saidlamp.

2. In a device of the c ass described, a motor, fan and heatingelements, a casing enclosing the same and having an enlarged mainportion, a tapering discharge portion leading from one side thereof, andan offset portion of restricted diameter extending from the oppositeside thereof, switches 'for said motor and heating elements mounted insaid offset portion, said offset portion being provided with openings toadmit air around said switches.

3. In a device of the class described, a motor, fan and heatingelements, a casin enclosing the same and having an enlarge main portion,a tapering discharge portion leading from one-side thereof, an offsetportion of restricted diameter extending from the opposite side thereof,and having an open end, a removable plate closing said open end, andswitches for said motor and heating elements mounted on the inner sideof said plate with control lugs projecting therethrough.

4. In a device of the class described, a motor having a frame, aforaminous member extending across one end of said frame, a secondforaminous member overlying said first mentioned member and projectingtherewith to formI an insulator holding clamp, a foraminous reflectoroverlying said second mentioned member, a screw extending through saidrefiector and members into said frame' for securing said members andreflectorin place on said frame, and a lamp in front of said refiector.l

5. In a device of the class described, a cylindrical housing, a fan anda motor nea-r one end thereof, an insulator carried Vby said motor,radially spaced circular heating eleath of the air stream from said fanon said insulator, a lamp in front of said heating elements a stationaryreflector for said lamp within the periphery of the innermost heatingelement and extendingbetween said lamp onnone side and said insulatorand said fan on ther'othe'r side, said reflector being adapted to permitthe passage therethroligh of air :from said fan.

6. In a evicepf the class described, a casing, a frame member, a motorcarried thereby, a fan driven by said motor, a stationary refiectormounted on said motor, an insulator carried on said motor and radiallyspaced circular heating elements on said insulator outside of theperiphery of said reflector, said insulator being between said fan andsaid reflector, a lamp mounted on said casing in front of saidreflector, said frame, insulator and refiector being ioraminous topermit the passage. of air therethrough from said fan and over saidlamp.

In testimony whereoi:` I hereunto affix my signature this 14th day ofDecember, 1928.
